SAN JUAN, Puerto Rico -- The Puerto Rico Tip-Off was a tournament of revelations, some of them rude: Its only ranked team (No. 9 North Carolina) finished 1-2 and made a strong argument to be unranked by Monday. Its lone preseason All-American (Tar Heels forward Harrison Barnes) was far more freshman-like than All-American-like. Its team with the most aggressive reputation (West Virginia) had its star player (Kevin Jones) admit of his opponent, following the championship game, "They were the aggressor, and they had us on our heels the whole night."
